WORK-:GUIDE FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Jan. 1. 1907.

Application filed February 14. 1903. Serial No. 143,424.

for Type-VVriters; and I do hereby declare the following to be a full, clear, and exact de-.

scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to guiding and cutting devices for single sheets or for the con-- tinuous sheet or ribbon of paper which may be taken from a roll and guided over the platen in a flat-platen type-writing machine.

The object of my invention is to provide devices ofsimple construction which will accurately guide a single sheet or a continuous sheet or ribbon of paper of variable widths or in variable positions from a roll over the platen. The means for this purpose embrace adjustable guides,which 1 have shown of various modified constructions. Another object is toprovide for conveniently cutting ofit' or otherwise detaching a comparatively short sheet of paper from the sheet or roll, either before 01' after it has been printed. I provide various modified construetions and arrangements of, devices for this purpose. i'

It is frequently desirable to use a continuous sheet or wide ribbon of paper from a roll, and in such case the ,roll may be conveniently mounted by journals in brackets or other attachments secured to the platen or table and the paper drawn off and guided into the printing position on the platen. The guides are placed in a convenient position on the platen and made adjustable to suit diflerent widths of aper or dilferent positions thereof on the paten.

The matter. constituting my invention will be set forth in the claim.

I will now describe the details of construction and arrangement of my improved devices by'referonce to the accompanying drawings, in which I Figure 1 re resents a perspective view of a type-writer p aten with my attachments applied thereto. Fig. 2 re resents a'similar view showing an adjustab ework-guide and other modifications. Fig. S-reprcsents a similar view showing a modified arrangement of the paper-clamp and detaching devices. Figs. 4. and 5 represent detailed views, partly broken away, of modified paper cutting or detaching devices. Fig. 6" represents a detail view of adjustable or lazy-tong guides simi-- lar to those shown in Fig.2. Fig. 7 represents a' top plan view of a portion of the track-frame anda lateral clamp having guidepins for the paper ribbon. Fig. 8 represents a similar view with the clamping-blade in a raised position. Fig. 9 represents a transverse section on the line a: 3:, Fig.7. Fig. 10 represents atop plan view of another form of a justable guide. Fig. 11 represents-a trans verse section and elevation thereof, and Fig.

.12 represents a top, plan view 'of another modified construction and arrangementof an adjustable guide.

The track-frameA, Fig. -7, and the platen C are arranged in the table B in the usual manner, and the platen may be either fixed or tiltable. To the track-frameA are secured .bracke ts'a'for holding the rod 0/ of the clampblades a as shown in Fig. 7 To the rear end of the platen C are secured two rearwardlyextending brackets 0, having openings or. j ournal-boxes for receiving the shaft d, which carries'the paper-roll D; The wide sheet or ribbon D of paper is drawn over the face of the platen, as shown in Figs. 1,2, and 3, and in order to secure its proper alinement I provide suitable lateral guides secured to the platen, which may be made'adjustable, as described below. The fixed guides E may be secured directlyto' the platen, as shown in Fig. 1, and are provided at their inner ends with flanges a, forming abutting edges for the paper. I preferably make the'guides E, E and E adjustable toward or from the edge of the platen. Suitable lateral supports 0 c are secured to the edge of the platen, as sh own in Fig. 2, and to such supports are pivotally desired position. The outer ends of the bars A modified construction-of an adjustable guide device is shown in Figs. and 11, in which a guide-pieceE is provided with a turned-up flange 0 at its inner end and with a longitudinal slot a through which is assed a set-screw b, which enters an. openmg or socket in the supporting-bar c It will be understood that by means of the slot e and set-screw ,b the guide-piece E can be adjusted outward or inward to suit the width of paper or the position of the sheetof paper on the platen.

It sometimes occurs that a longitudinallyadjustable guide is required for cards or other special form of paper to be printed, and for this purpose I provide a guide-piece Et, (shown in Fig. 12,) having an abutting edge e? and a longitudinal slot e through which is assed a set-screw 1) into the supporting b ock or bar 0 Since the paper is used in sheets of various sizes or in a continuous sheet or ribbon, I

rovide means for cutting it off into suitable engths, as'illu'strated in Figs. 1, 2, 3, 4, and 5. At the front edge of the platen I may secure a shearing-bar F, having a sharp outer edge, as one member of a shear or cutter, the

other member H of which is ivotally connected at one end either to the ar F or to the platen. In order to facilitate the operation and prevent'the paper sheet from slipping, I

provide a flexible resser-bar G, secured at its opposite ends to the edges of the platen, as shown at Fig. 1. Instead'ofa cutter H, I may simply provide a flexible presser-bar G,

" secured at the front edge of the platen, as

shown in Fig. 2, by means of which the paper may be detached by tearing it against the edge of the bar. In Fig. 4 there is shown a different form of presser-bar G, the same being provided with a beveled edge, and in Fig.5 there is still anotherform of this presserbar G the same having a serrated edge. Again, in Fig. 3 there is shown a further modification of the presser-barG The same having a sharp beveledfront edge may be se cured'at its back edge to a rod 9, resting in journal-boxes or suitable openings 9 of the brackets c. A handle 9 is applied to one end of the rod 9, and a coiledsprmg g is also secured to the rod for causing the bar g to act as a clamp and hear at its front edge upon the sheet ofpaper, as shown in Fig. 3. It will thus be seen. that the paper sheet may be cut or otherwise detached either at the front edge of the platen or at therearedge thereof. The paper sheet may also bedetached at the rear edge of the platen, either before or after being type-written or printed. The bar G, mounted in bearings, as shown in Fig. 3, may have its front edge sharpened or serrated, res ectively, of the same form as shown in I igs. 4 and 5, for facilitating the cutting operation.

The operation of my devices is verysimple and requires no extended descri tion to enable an operator .to properly ad ust and use them. The slot e in the bar e of the lazytongs guide device E is sufliciently curved to compensate for the varying length'of the arm or bar e by reason. of the movement of the bar or pin 1) in the slot, so as to maintain the parallel movement of the guide-pins a It is to be understood that I do not limit myself to any particular disposition of these guides, as they may be arranged wherever it may be desirable to meet the requirements of any particular work.

The paper-guiding device characterized by my invention is capable of being positionedover the platen stationarilyat a predetermined point, so that the work-sheet shall at all times be positioned and guided, and Whether in the forms illustrated in Figs. 1, 2, 10, .11, and 12 or in the form illustrated in Figs. 7, 8, and 9 the operative face of said "device-that is, that which is abutted bythe work-sheetis constructed and arrangedto be positioned relative to the work-sheet.

Having described my invention, what I claim, and "desire to secure by LettersPatent, 1s

In a type-writing machine, the comb'mation with the platen, of a paper-roll, the lazy- 'rco parallel movement of the guide-pins may be maintaihed, substantially as described.

In testimony whereof I afiix mysignature in the presence of two subscribing witnesses.
